A novel pressure-resistant oil-immersed proportional actuator, with a magnetic grid magnetic-isolated ring on its single-piece sleeve to replace the traditional nonmagnetic material magnetic-isolated ring, was designed to simplify manufacture process and minimize manufacturing costs. Magnetic simulation and experimental study were applied for both magnetic grid magnetic-isolated ring and nonmagnetic material magnetic-isolated ring proportional actuators. The results fit each other well and prove that, the working areas are 2.4 mm and 2.2 mm respectively, the maximum force outputs are 22 N and 15 N respectively, and they both have similar force output response characteristics. Hence, comparing to the traditional actuator, the novel proportional actuator has similar and good static and dynamic characteristics, and its applications to electro-hydraulic proportional valve are acceptable.
